Call 331-462-2711 Formaldehyde Regulatory agencies, including the EPA and the National Cancer Institute are reporting that elevated concentrations of formaldehyde in the air (0.1 ppm or 100 ppb) may cause individuals to experience adverse health effects. But how do we know the levels of formaldehyde in our environment? Our Services DOES FORMALDEHYDE CAUSE ANY OTHER HEALTH PROBLEMS? When formaldehyde is present in the air at levels higher than 0.1 parts per million (ppm), some people may have health effects, such as: Watery eyes Burning sensations of the eyes, nose, and throat Coughing Wheezing Nausea Skin irritation Scroll Down Formaldehyde does not affect all people the same. Some people have extreme sensitivity, while others have no reaction to the same level of exposure. Formaldehyde in consumer products such as cosmetics and lotions can cause an allergic reaction in the skin (allergic contact dermatitis), which can lead to an itchy, red rash which may become raised or develop blisters. HOW TO LIMIT YOUR EXPOSURE TO FORMALDEHYDE Before buying pressed-wood products, including building materials, cabinetry, and furniture, buyers should ask about the formaldehyde content of these products. The EPA recommends using "exterior-grade" products to limit formaldehyde exposure in the home. Do not smoke cigarettes or tobacco products indoors. People who are concerned about formaldehyde exposure from personal care products and cosmetics can avoid using products that contain or release formaldehyde. Still, because the amount of formaldehyde released from these products is low, it isn’t clear that this will provide any health benefit. Formaldehyde can be listed on a product label by other names, such as: Formalin Formic aldehyde Methanediol Methanal Methyl aldehyde Methylene glycol Methylene oxide Some chemicals that are used as preservatives can release formaldehyde, such as: Benzylhemiformal 2-bromo-2-nitropropane-1,3-diol 5-bromo-5-nitro-1,3-dioxane Diazolidinyl urea 1,3-dimethylol-5,5-dimethylhydantoin (or DMDM hydantoin) Imidazolidinyl urea Sodium hydroxymethylglycinate Quaternium-15 Blog 331-462-2711 Request Quote

Call 331-462-2711 PFAS in Drinking Water Current Status On May 18, 2026, EPA proposed two rules related to PFAS in drinking water. The first would rescind Biden-era regulations for PFHxS, PFNA, HFPO-DA, and Hazard Index mixtures . The second would extend the compliance deadlines for the PFOA and PFOS Maximum Contaminant Levels (MCLs) for two additional years, until 2031 . The comment periods for each rule close July 20, 2026. EPA also announced a public hearing will be held on July 7, 2026 where the public can provide comments on the rules. The deadline for registration to attend or provide verbal public comment is July 1, 2026. Last Updated 9/18/2026 Source: Environmental & Energy Law Program, Harvard Law School Why it Matters PFAS, often called “forever chemicals,” are a family of man-made chemicals featuring a strong carbon fluorine bond that makes the chemicals extremely durable. Studies have found significant PFAS contamination in the country’s public drinking water supplies. At high levels of exposure, PFAS have been shown to cause serious human health problems.The Biden-era PFAS rule under SDWA establishes deadlines for drinking water systems to test for PFAS by 2027 and to meet specific PFAS standards by 2029. The regulation is a significant step toward protecting public health as envisioned in EPA’s 2021 PFAS Strategic Roadmap. Source: PFAS Strategic Roadmap: EPA's Commitments to Action 2021 -2024 EPA's PFAS Strategic Roadmap: Three Years of Progress November 2024 EPA's Proposal to Remove Drinking Water Standards for Four PFAS Could Slow Future SDWA Rulemaking PFAS and the EPA Strategic Roadmap: Progress and Challenges Timeline Trump Administration II Sept. 18, 2026 The D.C. Circuit heard oral arguments in American Water Works Association, et al. v. EPA. May 18, 2026 EPA proposed two rules related to PFAS in drinking water. The first would rescind Biden-era regulations for PFHxS, PFNA, HFPO-DA, and Hazard Index mixtures. The second would extend the compliance deadlines for the PFOA and PFOS Maximum Contaminant Levels (MCLs) for two additional years, until 2031. The comment periods for each rule close July 20, 2026 . EPA also announced a public hearing will be held on July 7, 2026 where the public can provide comments on the rules. The deadline for registration to attend or provide verbal public comment is July 1, 2026 . April 6, 2026 EPA published its sixth draft Contaminant Candidate List (“CCL 6”) for public comment, which lists contaminants that are known or anticipated to occur in public water systems and may require regulation under the Safe Drinking Water Act (SDWA) in the future. PFAS were included on this list. EPA stated it will decide whether to regulate at least five contaminants from the CCL. Comments on CCL 6 are due June 5, 2026. March 19, 2026 The D.C. Circuit denied EPA’s request to sever and hold in abeyance challenges to drinking water standards for four Index PFAS that the agency now intends to repeal. American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.). Feb. 19, 2026 EPA filed a motion to sever and hold in abeyance claims related to Index PFAS regulations in American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.). In its motion, EPA stated it intends to “commence the rulemaking process imminently” to rescind the portion of the Biden-ERA PFAS drinking water rule that issues regulatory determinations and standards for the Index PFAS. Jan. 12, 2026 The D.C. Circuit issued an order denying EPA’s previous request to summarily vacate four of the six Biden-era PFAS drinking water rules. The court explained that despite EPA’s arguments that the rules were procedurally inadequate, the merits of the parties’ positions were “not so clear as to warrant summary action.” American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir. June 07, 2024). Sept. 11, 2025 EPA requested the D.C. Circuit vacate four of the six Biden-era PFAS drinking water rules, arguing that the agency failed to follow the Safe Drinking Water Act’s public comment procedures when issuing those standards. American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.). July 22, 2025 The D.C. Circuit granted EPA’s motion to reactivate the litigation regarding a challenge by industry and utilities to the Biden-era PFAS drinking water rule. American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.). May 14, 2025 EPA announced it will delay implementation of the SDWA Biden-era rule for two PFAS chemicals, PFOS and PFOA, extending the compliance deadline for drinking water suppliers to meet standards set for those two chemicals to 2031, providing water suppliers two additional years to comply. EPA also stated it will rescind the standards set in the Biden-era rule for four other PFAS chemicals. EPA expects to reissue a new regulation in spring 2026 and will continue to defend the other standards set in the Biden-era rule for PFOS and PFOA in the litigation challenging the rule. American Water Works Association, et al., v. EPA, (D.C. Cir. June 2024) Docket Number 24-1188. April 28, 2025 EPA announced it intends to address PFAS contamination . EPA also stated it will address concerns raised by water providers regarding the timing of the SDWA PFAS rule’s drinking water standards and monitoring deadlines. April 7, 2025 The court granted an unopposed EPA motion to extend the stay for 30 additional days. American Water Works Association, et al., v. EPA, (D.C. Cir. June 2024) Docket Number 24-1188. Feb. 7, 2025 The Court agreed to grant EPA’s motion to hold the case in abeyance for 60 days while EPA reevaluates the Biden-era rule. American Water Works Association, et al., v. EPA , No. 24-1188 (D.C. Cir.). Biden Administration June 7, 2024 Trade associations representing public water providers and industry challenged the EPA PFAS drinking water rule, arguing, among other issues, that EPA did not rely on the best available science, took unlawful novel approaches, and underestimated the costs of the regulation. Multiple environmental groups and 18 states have intervened in support of the rule. American Water Works Association, et al., v. EPA, No. 24-1188 (D.C. Cir.)., consolidated with other challenges to the rule. April 26, 2024 EPA, under the Safe Drinking Water Act, finalized the PFAS National Primary Drinking Water Regulation Rule, setting drinking water standards for certain PFAS chemical subtypes. The rule establishes legally enforceable levels, called Maximum Contaminant Levels (MCLs), for six types of PFAS in drinking water systems. For two other specific PFAS chemicals, EPA set Maximum Contaminant Level Goals (MCLGs), non-enforceable, health-based, public drinking water objectives, at zero.

Radon Levels Explained Radioactivity (and radon gas) results are measured in units of picocuries (pCi) [per liter of air] in the United States versus the International System of Units (SI), the Becquerel (Bq). A picocurie is a unit of radioactivity that is equivalent to one trillionth of a curie. In Perspective, one cure measures the rate of radioactive decay, specifically 3.7 x 10^10 disintegrations per second. What is an Action Level? The EPA recommends fixing homes when radon levels reach 4 pCi/L (150 Bq/m³) or higher. Since no known level of radon exposure is considered safe, the EPA also urges Americans to consider taking action when levels fall between 2 and 4 pCi/L (75–150 Bq/m³).

Identification, Characteristics, Common Uses & Health Risks Asbestos is a naturally occurring group of silicate minerals that was widely used throughout the construction, manufacturing, automotive, and industrial industries because of its strength, durability, fire resistance, and insulating properties. There are six recognized types of asbestos, classified into two mineral groups: serpentine and amphibole. Each type has distinct mineral characteristics, fiber structures, and historical commercial applications. Although some types were used extensively in building materials, others are more commonly encountered as naturally occurring mineral contaminants or impurities in commercial products. Asbestos remains an important environmental and occupational health concern because microscopic fibers can become airborne when asbestos-containing materials are damaged, disturbed, improperly handled, or deteriorated. Understanding the six types of asbestos can help property owners, contractors, environmental professionals, and building managers recognize potential hazards and make informed decisions about asbestos inspection and laboratory testing . What Are the Two Main Groups of Asbestos? The six recognized asbestos minerals are divided into two mineralogical classifications: 1. Serpentine Group Chrysotile (white asbestos) 2. Amphibole Group Crocidolite (blue asbestos) Amosite (brown asbestos) Tremolite Anthophyllite Actinolite The primary difference between these groups is their mineral structure and fiber morphology. Chrysotile generally has curved, flexible fibers arranged in layered structures. Amphibole asbestos minerals typically have straighter, more rigid, elongated fibers. Both groups contain asbestos fibers capable of causing serious disease when inhaled. 1. Chrysotile – White Asbestos Mineral classification: Serpentine Chrysotile, commonly referred to as white asbestos, is the most widely used asbestos mineral historically. It was incorporated into thousands of commercial and industrial products, particularly construction materials, because of its flexibility, tensile strength, heat resistance, and ability to be combined with other materials. Unlike amphibole asbestos, chrysotile has a layered mineral structure that produces curved or curly fibers. Physical Characteristics Typically white, grayish-white, or greenish-white. Curved, flexible, and often bundled fibers. Layered serpentine mineral structure. Resistant to heat and many chemical processes. Common Historical Applications Roofing shingles and roofing felts. Vinyl floor tiles and flooring adhesives. Cement siding and asbestos-cement products. Ceiling tiles and acoustic materials. Joint compound and textured wall coatings. Pipe and boiler insulation. Gaskets and industrial sealing materials. Automotive brake linings and clutch components. Health Risks Chrysotile is a known human carcinogen. Inhalation of its fibers has been associated with mesothelioma, lung cancer, and asbestosis. Although chrysotile has historically been described as less bio-persistent than amphibole asbestos, it should never be considered safe to inhale. 2. Crocidolite – Blue Asbestos Mineral classification: Amphibole Crocidolite, commonly known as blue asbestos, is an amphibole mineral recognized for its fine, straight, needle-like fibers. It has historically been considered one of the most hazardous forms of asbestos because its fibers are durable and can remain in lung tissue for extended periods. Crocidolite was used in certain industrial and commercial applications, although its use was considerably less widespread than chrysotile. Physical Characteristics Blue to blue-gray appearance in mineral specimens. Straight, fine, elongated fibers. Rigid amphibole crystal structure. High resistance to chemical degradation. Common Historical Applications Certain spray-applied insulation products. Asbestos-cement products and pipes. Thermal insulation. Industrial heat-resistant materials. Historical gas mask filters. Certain historical filtration applications. Health Risks Crocidolite exposure is strongly associated with mesothelioma and lung cancer. Its durable fibers can persist in the respiratory system following inhalation. Because of its potential health consequences, crocidolite-containing materials require careful professional assessment and appropriate handling. 3. Amosite – Brown Asbestos Mineral classification: Amphibole Amosite, commonly referred to as brown asbestos, is an amphibole asbestos mineral that was historically used in construction and industrial applications, particularly where thermal insulation and fire resistance were required. Amosite fibers are generally straight, brittle, and elongated. The mineral was frequently incorporated into insulation boards and other manufactured building materials. Physical Characteristics Typically brown, gray-brown, or gray-green. Straight, brittle fibers. Amphibole mineral structure. High resistance to heat. Common Historical Applications Thermal insulation. Pipe and boiler insulation. Insulating boards. Ceiling tiles. Fireproofing materials. Commercial building insulation. Industrial equipment insulation. Health Risks Amosite is a carcinogenic asbestos mineral associated with mesothelioma, lung cancer, and asbestosis. Materials containing amosite can release respirable fibers when cut, drilled, broken, sanded, or otherwise disturbed. 4. Tremolite Asbestos Mineral classification: Amphibole Tremolite is an amphibole mineral that occurs naturally in metamorphic rocks and certain mineral deposits. When tremolite develops an asbestos-like fibrous structure, it is classified as tremolite asbestos. Unlike chrysotile and amosite, tremolite was not widely used as a primary commercial asbestos product. Its significance is often related to its occurrence as a contaminant in other mineral materials. Physical Characteristics White, gray, green, or translucent mineral specimens. Can occur in fibrous, elongated, or non-fibrous crystalline forms. Amphibole mineral structure. Fibrous varieties may have straight, needle-like characteristics. Where Tremolite May Be Encountered Naturally occurring mineral deposits. Certain contaminated vermiculite materials. Some talc and other mineral products. Certain geological formations. Occasionally as an impurity in commercial materials. Health Risks Fibrous tremolite is hazardous when inhaled and has been associated with mesothelioma, lung cancer, and asbestosis. An important distinction is that not every tremolite mineral specimen is asbestos. Its classification depends on the mineral's fibrous form and characteristics. 5. Anthophyllite Asbestos Mineral classification: Amphibole Anthophyllite is a naturally occurring amphibole mineral that can develop an asbestos-like fibrous structure. It is less commonly encountered than the major commercial asbestos types. Historically, anthophyllite asbestos had limited industrial applications. It is more frequently discussed in connection with naturally occurring mineral deposits and potential contamination of other materials. Physical Characteristics Typically white, gray, brown, or greenish. Fibrous or elongated crystalline structure. Straight, brittle fibers when present in asbestos form. Amphibole mineral composition. Where Anthophyllite May Be Encountered Naturally occurring mineral deposits. Certain historical insulation products. Some contaminated mineral materials. Certain industrial and construction applications. Health Risks Fibrous anthophyllite is a recognized asbestos hazard. Inhalation can contribute to asbestos-related diseases, including lung cancer, mesothelioma, and asbestosis. As with tremolite, the presence of the mineral anthophyllite does not automatically mean the material contains asbestos. Its physical form and mineralogical characteristics must be evaluated. 6. Actinolite Asbestos Mineral classification: Amphibole Actinolite is an amphibole mineral that occurs naturally in several geological environments. When it develops an asbestos-like fibrous structure, it is classified as actinolite asbestos. Actinolite was not commonly manufactured or marketed as a primary commercial asbestos product. However, fibrous actinolite can occur as a contaminant in certain mineral materials and naturally occurring deposits. Physical Characteristics Typically green, gray-green, or dark green. Can occur as elongated or fibrous crystals. Straight, needle-like fibers in fibrous forms. Amphibole mineral structure. Where Actinolite May Be Encountered Naturally occurring mineral deposits. Certain contaminated mineral products. Some insulation and construction materials. Geological formations containing amphibole minerals. Health Risks Fibrous actinolite is hazardous when inhaled and is associated with asbestos-related diseases, including lung cancer, mesothelioma, and asbestosis. Laboratory identification is necessary to distinguish fibrous actinolite from other amphibole minerals and non-asbestiform mineral varieties.

Actual identification requires appropriate mineralogical examination. What Health Problems Can Asbestos Exposure Cause? Asbestos exposure is associated with several serious respiratory diseases and cancers. Health effects may not become apparent until many years or decades after exposure. The primary asbestos-related diseases include: Mesothelioma Mesothelioma is an aggressive cancer that develops in the mesothelial lining surrounding certain internal organs, most commonly the lungs (pleura). Asbestos exposure is the principal established cause of malignant mesothelioma. Asbestos-Related Lung Cancer Inhaled asbestos fibers can contribute to the development of lung cancer. Smoking combined with asbestos exposure significantly increases lung cancer risk. Asbestosis Asbestosis is a chronic lung disease caused by inhalation of asbestos fibers. The resulting inflammation and scarring of lung tissue can lead to shortness of breath, reduced lung function, and progressive respiratory impairment. Pleural Diseases Asbestos exposure can cause changes to the pleura, the membrane surrounding the lungs. These conditions may include pleural plaques, pleural thickening, and pleural effusions. The likelihood of developing asbestos-related disease depends on several factors, including the amount of exposure, duration, frequency, fiber characteristics, and individual circumstances. All six recognized asbestos types are considered carcinogenic to humans. Where Is Asbestos Commonly Found in Buildings? Asbestos was incorporated into many construction materials because of its durability, insulating properties, and resistance to heat and fire. Older residential, commercial, industrial, and institutional buildings may contain asbestos-containing materials. Common locations include: Roofing and Exterior Materials Roofing shingles. Roofing felts. Cement siding. Exterior wall panels. Certain roofing adhesives. Interior Building Materials Vinyl floor tiles. Flooring adhesives and mastics. Ceiling tiles. Textured ceiling coatings. Joint compound. Wall plaster. Drywall-related materials. Mechanical and Insulation Systems Pipe insulation. Boiler insulation. HVAC insulation. Duct insulation. Thermal insulation blankets. Gaskets and mechanical seals. Fireproofing and Specialty Materials Spray-applied fireproofing. Insulating boards. Fire-resistant panels. Certain industrial coatings. Asbestos-cement products. The presence of these materials does not automatically mean asbestos is present. Building age, manufacturer, product history, and laboratory findings all help determine whether a material contains asbestos. How Can You Tell If a Material Contains Asbestos? One of the most common misconceptions about asbestos is that it can be identified by its appearance. In reality, asbestos fibers are microscopic and cannot reliably be identified by looking at a building material. Two materials may have identical appearances but completely different compositions. Likewise, materials that appear damaged, discolored, or deteriorated are not necessarily asbestos-containing materials. The only reliable way to establish whether a suspect material contains asbestos is through appropriate sampling and laboratory analysis. Property owners and contractors should avoid disturbing suspected materials until an appropriate assessment has been completed. How Is Asbestos Testing Performed? Professional asbestos testing typically involves an assessment of suspect building materials, appropriate sample collection, and laboratory analysis. The process generally includes the following: 1. Building and Material Assessment An asbestos professional evaluates the building, its age, construction materials, and areas where asbestos-containing products may have been installed. 2. Suspect Material Identification Materials are identified for potential sampling based on their appearance, location, composition, and historical use. 3. Sample Collection Samples are collected using appropriate procedures designed to minimize the release of airborne fibers. Sampling should be performed by qualified professionals in accordance with applicable regulations and project requirements. 4. Laboratory Analysis Samples are submitted to a qualified laboratory for analysis. Common analytical methods include: Polarized Light Microscopy (PLM): A commonly used method for identifying and estimating asbestos content in bulk building material samples. Transmission Electron Microscopy (TEM): A higher-resolution analytical technique that may be appropriate when additional fiber identification or sensitivity is required. The appropriate analytical method depends on the material, project requirements, and applicable regulations. Not every sample requires both methods. 5. Laboratory Results and Reporting Laboratory findings document whether asbestos was identified, the reported type when determined, and the estimated concentration when applicable. Results should be interpreted in the context of the building assessment, material condition, and intended renovation or demolition activities. How many types of asbestos are there? There are six recognized types of asbestos: chrysotile, crocidolite, amosite, tremolite, anthophyllite, and actinolite. They are divided into two groups: serpentine and amphibole . What is the most common type of asbestos? Chrysotile, also known as white asbestos, was historically the most widely used commercial asbestos mineral. It was incorporated into numerous roofing, flooring, insulation, cement, and construction products. Which type of asbestos is considered the most dangerous? Crocidolite is generally considered one of the most hazardous asbestos types because of its fine, durable fibers and strong association with mesothelioma. However, all six types are carcinogenic and should be treated as potential health hazards. Is chrysotile asbestos less dangerous than amphibole asbestos? Chrysotile and amphibole asbestos differ in fiber structure and biological persistence. Amphibole fibers generally remain in lung tissue longer, and exposure may carry a higher mesothelioma risk. However, chrysotile is also a known human carcinogen and is not safe to inhale. Can asbestos be identified by color? No. The terms white, blue, and brown asbestos are historical mineral descriptions, not reliable field identification methods. Asbestos fibers may be microscopic, and building materials frequently contain mixtures of different substances. Can asbestos be found in newer buildings? Yes. Although many asbestos uses have been restricted or banned in the United States, certain legacy products remain in buildings, and some asbestos-containing products have continued to be imported or used in specific applications. Building age alone cannot establish whether asbestos is present. Does asbestos have an odor? No. Asbestos fibers are odorless and cannot be detected by smell. Is asbestos dangerous if the material is not disturbed? Asbestos-containing materials in good condition that remain intact and undisturbed generally present a lower immediate risk of fiber release. However, damaged, deteriorating, or disturbed materials can release fibers into the air. Should I test for asbestos before remodeling my home or commercial property? If suspect materials may be affected by renovation, repair, or demolition, an asbestos assessment should be completed before work begins. Applicable federal, state, and local requirements may also require inspection or testing. Can I collect an asbestos sample myself? Sampling can release asbestos fibers if performed improperly. It is generally best to have suspect materials assessed and sampled by a qualified asbestos professional. Some jurisdictions require specific licensing or certification for asbestos inspection and sampling. When Should You Contact an Asbestos Testing Professional? An asbestos assessment may be appropriate when: Purchasing an older residential or commercial property. Planning a renovation or remodeling project. Preparing a building for demolition. Replacing flooring, roofing, or insulation. Repairing damaged pipe or boiler insulation. Managing commercial or industrial properties. Investigating suspected asbestos-containing materials. Responding to contractor or employee concerns about potential exposure. Early identification can help property owners and project managers make informed decisions, reduce the potential for unnecessary exposure, and plan renovation or demolition activities appropriately. Asbestos in Popcorn Ceilings: Identification, Testing, and Risk Popcorn ceilings installed before 1980 frequently contain asbestos fibers and should be tested before disturbance. How to Identify Asbestos Popcorn Ceilings Visual inspection alone is NOT sufficient. Laboratory testing is required. Testing Process 1.Sample collection by certified inspector 2.Chain-of-custody documentation 3.Laboratory analysis (PLM) Health Risks Disturbing asbestos releases airborne fibers that can be inhaled and cause long-term disease. When You Need Testing •Before renovation •Before demolition •Real estate transactions •Damage or deterioration Professional Testing vs DIY Asbestos Testing DIY kits are unreliable and often rejected in real estate and regulatory environments.
